Abstract
A method for producing at least one electrochemical cell of a solid-state battery, comprising a mixed-conducting anode, a mixed-conducting cathode, and an interposed electrolyte, is characterized in that a mixed-conducting anode and a mixed-conducting cathode are initially produced or provided. The surface of at least one of the two electrodes is modified by way of an additional method step in such a way that the electronic conductivity perpendicular to the cell is reduced to less than 10S/cm in a layer of the electrode near the surface. The anode and cathode are then assembled to form a solid-state battery in such a way that the surface-modified layer of at least one electrode is disposed as an electrolyte layer between the anode and cathode, and the mixed-conducting electrodes are thereby electronically separated.
